Abstract: I will review some recent results in the construction of the Sine Gordon model in hyperbolic signature in the setting of perturbative algebraic quantum field theory. One focus is on the construction of a Haag Kastler net of observables (of operators on a Hilbert space), the other will be to explain how the adiabatic switching function can be removed in expectation values in thermal states. The methods presented are a mixture of "old and new" in constructive and algebraic quantum field theory.

This is joint work with Kasia Rejzner, Klaus Fredenhagen, and Nicola Pinamonti.
